Cadmium(II) and lead(II) extraction and transport through polymer inclusion membranes with 1-alkylimidazole was written by Radzyminska-Lenarcik, Elzbieta;Pyszka, Ilona;Urbaniak, Wlodzimierz. And the article was included in Desalination and Water Treatment in 2021.COA of Formula: C11H20N2 This article mentions the following:
The formation of cadmium(II) complexes with hydrophobic 1-alkylimidazoles (1-hexylimidazole (1), 1-heptylimidazole (2), 1-octylimidazole (3), 1-decylimidazole (4) was tested by liquid-liquid partition method. On the basis of the extraction data, stability constants of cadmium(II) and Pb(II) complexes were determined It had been assumed that differences in the formation of cadmium(II) and lead(II) complexes with alkylimidazoles could be used to sep. those ions. The possibility of cadmium(II) and lead(II) ion separation in the transport through polymer inclusion membranes (PIMs) was examined PIMs comprising of cellulose triacetate, o-nitrophenylpentyl ether, and alkylimidazole (1-4) were used. The membranes were characterized using at. force microscopy (AFM). The results have shown that cadmium(II) ions are effectively transported through PIMs. The best result achieved for cadmium(II) removal from Cd(II)-Pb(II) solution for PIMs with (4) was 95.5% after 24 h. For this membrane, the separation coefficients for Cd(II)/Pb(II) were 1.62. Best Cd(II)/Pb(II) selectivity coefficients equal to 2.94 were found for (1). The influence of the basicity of carrier mols. on transport kinetics was discussed as well. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7COA of Formula: C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.COA of Formula: C11H20N2
